ssm框架

发表于 • 字数统计 14837 • 被 1189 人看爆

SSM框架，即Spring + Spring MVC + MyBatis的缩写，这个是继SSH之后，目前比较主流的Java EE企业级框架，适用于搭建各种大型的企业级应用系统。

准备工作

  1. 数据库
  2. IDE(集成开发环境),这里我用的是IntelliJ IDEA

步骤

创建maven项目并添加所需要的依赖

<properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <maven.compiler.source>1.7</maven.compiler.source>
        <maven.compiler.target>1.7</maven.compiler.target>
        <!-- 初始化spring版本 -->
        <spring.version>5.0.5.RELEASE</spring.version>
    </properties>
